The 4 cylinder 911 engine POLO 4. Type 930/4
I was invited out to Dean Polopolus' house yesterday to drive a 356 with a Polo 4 in it. I thought I should share my interesting experience. For those of you who don't yet know about the engine - it is an aftermarket engine based on the 911 air cooled 6cyl but with only 4 cylinders. The advantage is an engine that puts out the same or more power as the 6cyl counter part but weighs 100 pounds less and fits into small spaces.
Displacement can be anywhere from 2.0L to 2.7L, although Dean is positive that the engine will go up to 3.0L. Horsepower is over 200+ although Dean says 300+ can be achieved.
Right now this engine is best suited for 356 cars. No one has put one in a 912 as of yet. If one were to build a 912P or 912 Polo car then 911 cars would have a fearsome adversary. I would love to do one of these on a short wheel base 912 someday.
It is hard to describe driving this engine. Different than a 911 engine and more thrilling than any 4 cylinder engine. It would be worth having a 911 w/6cyl on one side of the garage and a 912 w/Polo 4 on the other side of the garage. Without a doubt the thrill factor is amazing. A must for the guy that has everything but wants something different. It is very torquey and has a power band up to 5500rpm. It kind of feels like a 911E engine with a different exhaust note. Light weight and peppy. More power and better reliability than a 4 cam engine. Dean has these available in kit form and complete engines, someday I would love to come up with a car to put one of these in.
